Only if you bought them from DEC after 1979, circa VT100. I've got (or had) a Beehive, ADM-3, Teleray 1060, Teleray 11M, ACT-V, a genuine DEC VT50, DEC VT52, DEC LA36 (DECwriter II), DEC LA120 (DECwriter III), a GE Terminet KSR printer, Radio Shack DT-1, and a Wyse 75 (aka DT-100) AND ALL of these produce 0x08 when you hit the backspace key, just like the Teletype ASR33/35/37s all did, the original DUMB terminals. So did the Singer terminals and a dozen brands long forgotten. Few, if any, had an option for changing what code the backspace key produced away from 0x08. Even Hayes AT-compatible modems recognize 0x08 as a backspace by default, not ^?. Sending ^? for as a substitute for backspace came along much later in isolated equipment and as such is incompatible. That's why in the ASCII chart 0x08 is called BACKSPACE. :-) Frank Durda IV <uhclem@nemesis.lonestar.org>|"The Knights who say "LETNi" or uhclem%nemesis@rwsystr.nkn.net | demand...
